On installation the git repository is initialized inside the $PRINTER_DATA_FOLDER/config directory.
In the remove script the deletion of .git and .gitignore is incorecctly trying to delete the files in the $PRINTER_DATA_FOLDER directory.
Added "/config" to fix this.
When removing git-backup using the installer, there are still some processes left running in the background.
To ensure a clean removal, and prevent problems on reinstallation, these processes should be killed on removal.
